UCLA study links common pesticide chlorpyrifos to higher Parkinson’s risk

A UCLA-led study found long-term residential exposure to the pesticide chlorpyrifos is linked to more than a 2.5-fold increase in Parkinson’s disease risk. Lab experiments in mice and zebrafish suggest chlorpyrifos damages dopamine neurons by disrupting autophagy, offering insight into the disease mechanism and potential therapeutic targets and underscoring the need for monitoring exposed individuals.
